Answer:
The answer is c
Step-by-step explanation:
Total weight of three items is 2.875 pounds
<em><u>Solution:</u></em>
Given that,
Maya is packing her backpack for hike
From given,
<em><u>How much weight do these three items add to her backpack?</u></em>
Add all these together
Thus total weight of three items is 2.875 pounds
I'm not sure but I think, f(s)=-4[x]-3
We move all terms to the left:
+31x+32)-((+5)=0
So your answer is 0
The described picture frame can be visualized into two separate parts. The first area is equal to the area using the outermost dimensions for the length and width.
Area = Length x Height
Area = (20 in) x (14 in)
Area = 280 in²
We are given that the area is only equal to 192 in². We subtract this value from the computed area.
Difference = 280 in² - 192 in²
difference = 88 in²
This area is equal to the area of the hollow space inside the frame. That is equal to,
height = 20 in - 2x
length = 14 in - 2x
The area,
88 = (20 - 2x)(14 - 2x)
Simplify the right hand side of the equation.
88 = 280 - 68x + 4x²
Divide the equation by 4,
22 = 70 - 17x + x²
Transposing,
x² - 17x - 48 = 0
The factors of the equation is 58.2.
Thus, the thickenss is equal to 58.2 in
